To all whom t may concern.'

Be it known that I, ANDREW BINDER, a citizen of the United States,` residing at Blakeslee, in the county of Fergus and State of Montana,`have invented av new and useful Explosive-Engine, is a specification. v

My invention relates to explosive engines, and the main object is t0 provide an engine with a cylinder that may be adjusted toward' the piston and thus take up wear of the pis-v ton against the sides of the cylinder. Auni other object is to provide an explosive engine with parts so arranged that at the ends of each stroke of the piston the stroke is cushioned either by internal gas pressure or by external air pressure rendered operative by vacuum within the engine.

ln the accompanying drawing, Figure l is a longitudinal section as on the line c--c Fig. 5, of an explosive engine embodying my invention. Fig. 2 is a cross section of said `engine on the line a-a Fig. l. Fig. 3 is a rear end elevation of said engine. Fig. 4f is a cross section on the line 5 5 Fig. 1. Fig. 5 is a top or plan view of the engine. Fig. 6 is a front end elevation of the upper half of the cylinder.

Referring to the drawing by reference numerals, 1 and 1 designate the main frame, 2 the crank shaft, 3 the iy wheel, 4; the connecting rod and 5 the cylinder of a simple engine driven by explosions of either coal gas or gas from gasolene or other gas producing fluid. rlhe cylinder is composed of a lower half 5 and an upper half 6, the latter fitting snugly between the vertical side eX-' tensions 5@- of the lower half, and is itself formed with upstanding side walls 6a and end walls 6b and 6 to form a water cooling tank l upon the upper halt of the cylinder.

Said Vupper half of the cylinder has its front end (the end nearest the crank shaft) provided with strong lateral flanges 8 (see Fig. 6) having slotted holes 9 for bolts l0 by which they are secured to the front end of the main frame in a vertically adjustable manner so as to permit the upper halt of the cylinder to be adjusted downward upon the piston. To hold the upper halt' cylinder lirmly in any adjusted position the top of the main frame is provided with two bridge bars 11 having screws 12 bearing with their points upon lugs i3 upon thevend walls oi of which the followingv the water tank part of the upper cylinder member.

'lo prevent escape of gas between the two members of the cylinder one member is provided with soft packing strips 14 contacting with the other member and firmly held by metal strips 15 and screws 16 upon the top edges of the water tank 7. And at the rear end of the cylinder are secured by screws .17X similar vertical strips 17 and soft strips 18 to close the joints 19 (see Figs. 1 and 3), while the lower part of the end wall 6b may simply be held tightly against the hollow cylinder cover 20, which cover is secured lby bolts 21 to the rear end of the lower cylinder member.

rl`he last mentioned member may be formed integral with the main frame, but between the 'two is :formed the usual water jacket 22 which communicates with the water tank across the walls 5 and 6au (see Fig. 2) so that the heated water may flow upward and the cooler water downward.

Secured between the cylinder head 20 and the rear end of the cylinder is the peripherie flange 23 of a sleeve or hollow cylinder head extension 24:, which extends into the cylinder and into a sleeve-like piston 25, which is provided with the usual pin 26 in the rear end of the connecting rod 4.

Said piston is provided with a packing ring 27 to make it fit tightly in the cylinder, and the sleeve or tubularhead 24 is provided with several packing rings 28 to make it lit tight within the sleeve piston. Said head extension is lubricated by an oil tube 29 having its intake at 30 (see Fig. l). Surplus oil or other matter may be let out through a tube 31 and pet cock 32. The outer side of the piston sleeve is oiled through an oilv hole 33. 34 is a pet cockto drain out the water and 35 is a smaller pet cock for emptying the space 36 in rearot the piston sleeve.

The central opening 3. in the'fhead extension is oval in cross section, as shown in Fig. l so as to communicate at its rear end with the chamber in the cylinder head 20, where the usual igniting plug 38 is located..and which is provided with an intake 39 and an exhaust l0 of so well known construction that no further illustration and description is considered necessarl rlhe water in the tank communicates also about half way l with the spaces 41 in the head sleeve 24 and the space #l2 in the head through apertures 43, 44, 45.

In the operation of the machine the piston on its forward stroke sucks in gas through the valve 39 from a mixer or carbureter (not shown). The gas is then compressed by the piston and ignited in any suitable manner; the explosion now gives the piston a powerful forward `push but before the forward stroke is finished the piston is resisted by atmospheric pressure at its front end, owing t0 vacuum in the space 3G at the rear end of it. And when the piston is finishing its rearward stroke it is cushioned by the compressed air which is found in the space 3G but which is not suliicient in quantity to ill the space when the piston is at the forward end of the stroke. In this way the crank shaft and other parts of the engine are relieved of the usual blow caused by the momentum of the piston and connecting rod at the ends of each stroke.

That I claim is:

In an engine, a cylinder composed of two semieylindrical members fitted one into the other, a piston. within the cylinder, and means for adjusting and holding one member of the cylinder toward the other member so as to thereby take up wear of the piston against the sides of the cylinder, said. cylinder larranged in horizontal position and the upper member of it formed with a tank adapted to hold cooling water, and a water jacket arranged about the cylinder and communicating with said tank.

In testimony whereof I aix my signature.

ANDREW BINDER.
